l Docket No. 50-334, License No. DPR-66 Emergency Response Data System (ERDS)

In accordance with the requirements published in NUREG 1394, Rev. 1, Section 3.6, " Administrative Implementation Requirements,"

the enclosed Data Point Library (DPL) changes are being submitted.

These three (3) DPL's have undergone a change in their Hi alarm setpoints. These changes are currently in effect on the Beaver valley Plant computers which provide the data to the ERDS computer.

Any questions regarding these DPL changes should be addressed to Joe Senko at (412) 393-5728.

Sincerely,
